Chinese researchers have revealed that plant growth is significantly limited by phosphorus supply in both the tropics and temperate regions and in all major types of terrestrial ecosystems including forests, grasslands, tundras, and farmland.
　　Phosphorus is considered a crucial nutrient elemen...

　　Cadmium (Cd) is one of the most serious heavy metal pollutants. It brings a great threat not only to human health but also to crop production. An excess amount of Cd in soil reduces the efficiency of plant photosynthesis, absorption of water and nutrients, and growth.
　　Therefore, enhancin...

　　In terrestrial ecosystems, nitrogen (N) and phosphorus (P) have been considered as the most important limiting nutrients of aboveground plant production. P limitation, however, is usually assumed to occur mainly in the strongly weathered lowland tropical regions but rarely elsewhere. Here we...

　　With the development of economy and the acceleration of urbanization, human activities have led to the pollution of harmful heavy metals in large areas of farmland, especially paddy soil. Cadmium (Cd) is a common toxic metal in soil pollution. The nationwide survey of soil pollution in China...

　　Tropical and subtropical forests are considered sources of nitrous oxide, one of the greenhouse gases mainly produced via microbial nitrification and denitrification in soil. However, in recent decades, the emission of nitrous oxide has been influenced by increasing atmospheric nitrogen (N) ...
